My judgementalism has primarily been limited to my experiences in the horsey world; those who treat their horse like a motorbike basically - from expecting to show up and the horse be tacked up and ready and they hop on and off they go, and the reverse when they come back. People who don't generally look after their horses well - left in a stable all day, with making sure that enough hay, water, skipped out etc etc (let alone the whole keeping them in when not necessary). Coming to a yard and behaving in a rude and entitled manner (and all ages do this, from teenagers, to grannies), not trying to work with the situation they are coming into, especially wrt horses needing to get to know one another, and some general rules that are in place (usually influenced strongly by me, I must admit).
Basically, people who have horses when they shouldn't - and that includes a dear- but very spoilt - friend of mine who, in a wheelchair and no upper body strength, persuaded her parents to buy her a pony and trap and then expected others to undertake care and risk their own lives and hers - and the pony's - while her blasted parents just sat back and humoured her.
(And yes, there was a danger to life when her very heavy wheelchair almost upended the trap with my friend trying to get it going, which in turn, nearly lifted the pony off the ground. It was never tried again.)
I also judge use of language, eating in the street (unless chips at the coast) - and spelling, although the latter, less so these days due to voice apps and autocorrect and - no editing! (I type on my laptop in low light and often make stupid mistakes I didn't spot until submitted....)
All of that said, I know that I am judged in many many ways - including for being judgemental and "looking down my nose" at people (sigh). By and large though, my own criticisms usually connected with horses, animals, general rules of life (safety, littering etc.) and unkindness.
Oh, and I also judge the Mormon branch of my family - for being Mormons.
